Medical Intelligence & Overview
Paravaccinia, also known as milker's nodule or pseudocowpox, is a viral skin infection caused by the parapoxvirus. It typically affects those who handle infected animals or animal products. When classified as 'unspecified,' it indicates that the exact presentation or location of the infection hasn't been detailed. This condition usually manifests as skin lesions, primarily on the hands or arms, and can be mistaken for other skin ailments. Although generally benign, understanding the nature of paravaccinia helps in proper recognition and management.
